Parker 26 Series Fittings is a permanent (crimp) style fitting which permits quick assembly with our family of Parker crimpers. Assembly of No-Skive hose and fittings does not require removal of the outer cover of the hose. This eliminates premature hose failure caused by skiving too long or short. 26 Series Fittings has zinc dichromate plating and are used with 201-261, 206, 213, 221FR, 225, 235, 244, 266, 285, 293, SS23CG Hoses - the Parker Engine_Airbrake_Marine_Gas Hoses.
